Two state legislative chambers, the Michigan and Minnesota state Houses, changed party control following the 2024 general election. Republicans won control of the Michigan House from Democrats, and secured a tie in the Minnesota House.

There were elections for the members of 85 of the nation's 99 legislative chambers in 2024, representing 5,807 of the country's 7,386 state legislative seats (79%). Heading into the elections, Democrats controlled 33 of those chambers, Republicans controlled 50, and two chambers had power-sharing agreements. Afterwards, Democrats controlled 31, Republicans controlled 51, two had power-sharing agreements, and one was tied.

In total, Democrats controlled 39 chambers after the 2024 elections, Republicans controlled 57 chambers, power-sharing coalitions controlled two chambers, and one chamber was tied.

As a result of the 2024 elections, Democrats had a net loss of 32 state legislative seats, Republicans had a net gain of 42 seats, and Independents and minor party officeholders had a net gain of 16 seats.

Most chambers saw minor changes to partisan composition. Republicans recorded their biggest gains in New Hampshire, Maine, Michigan, and Vermont. Republicans expanded their majority in both New Hampshire chambers, reduced the Democratic majority in both Maine legislative chambers, won control of the Michigan House and broke the state’s Democratic trifecta, and broke the Democratic supermajority in Vermont.

Democrats recorded their biggest gains in Montana and Wisconsin. Democrats broke the Republican supermajority in Montana and in the Wisconsin Senate.

Democratic trifectas in Michigan and Minnesota were lost as a result of the 2024 elections. Republicans neither gained nor lost trifectas.

Forty-four states held elections for at least one state legislative chamber. Heading into the elections, 15 of those states had Democratic trifectas, 20 had Republican trifectas, and nine had divided governments. Afterwards, 13 had Democratic trifectas, 20 had Republican trifectas, and 11 had divided governments.

In total, there were 17 Democratic trifectas, 23 Republican trifectas, and 10 divided governments before the 2024 elections. After the elections, there were 15 Democratic trifectas (a loss of two), 23 Republican trifectas, and 12 divided governments (an increase of two).

Veto-proof supermajority status changed in seven states. Democrats lost supermajority status in New York and Vermont and gained it in Connecticut. while Republicans lost supermajority status in Montana and North Carolina and gained it in Iowa and South Carolina.

Of states that held legislative elections in 2024, eight state legislatures had Democratic supermajorities in both chambers, 18 had Republican supermajorities in both chambers, and neither party had a supermajority in 18 states before the election. After the election, seven state legislatures had Democratic supermajorities in both chambers, 18 had Republican supermajorities in both chambers, and neither party had a supermajority in 19 states.

In total across all 50 states, there were veto-proof majorities in 29 state legislatures before the election—nine Democratic and 20 Republican. After the election, there were veto-proof majorities in 28 state legislatures—eight Democratic (a loss of one) and 20 Republican.

Heading into the 2024 elections, four states had a governor of one party and a veto-proof state legislative majority of the opposing party: Kansas, Kentucky, North Carolina, and Vermont. After the elections, Kansas and Kentucky maintained that status, North Carolina and Vermont lost that status, and no new state became a veto-proof legislature with an opposing party governor.

    Three legislative leaders who were defeated in primaries in 2024 were Republican state senators, and one was a Democratic House member. One Republican served as president, one as president pro tempore, one as majority leader, and one Democrat served as speaker.

    Democratic PartyValerie Longhurst
    See also: Valerie Longhurst

    First elected in 2003, Longhurst had served as Delaware's speaker of the House from 2023-2024.[183] Longhurst was previously the House Majority Whip from 2008-2012 and the House Majority Leader from 2012-2023.[183] Longhurst lost the Democratic primary to Kamela Smith (D) 53.3%-46.7%. During the primary, Longhurst's campaign website said, "Representative Valerie Longhurst has been diligently serving members of the 15th District since 2004 and has been instrumental in passing important, impactful legislation in various policy areas, including: mental and behavioral Health, quality public education, public safety and criminal justice reform, environment and energy, economic empowerment, health and quality of life, [and] women’s issues."[184]

    Delaware Online's Shane Brennan said, "Voter turnout was consistently slow. Signs and workers representing state house representative candidates were not as common or visible as candidates for Wilmington, New Castle County and governor races."[185][186] Smith was endorsed by the Working Families Party during the primary, and said, "Once I’m in Dover, I’ll be pushing for government transparency, better education, health care, and housing, and the investments in our people that they deserve."[187][185]

    Democratic PartyScott Saiki
    See also: Scott Saiki

    First elected in 1994, Saiki had served as Hawaii's speaker of the House since May 2017. Saiki was previously the House majority leader from 2013-2017. Saiki lost the Democratic primary to Kim Coco Iwamoto (D) 49.3%-44.6%.[188] During the campaign, Saiki's campaign website said, "When I think about the future for Hawaiʻi, I think about how we can create a more affordable Hawaiʻi. I believe that we need to address the root causes of why so many local families struggle: cost of living, housing that can be affordable for all, and public safety so that our ʻohana can thrive."[189]

    Spectrum News' Michael Tsai said local media expected a close race between Saiki and Iwamoto after the two candidates had competed against each other in the previous two election years. Tsai said, "Saiki had defeated Iwamoto by less than 200 votes in each of the last two elections...Iwamoto, an attorney and former state Board of Education member, previously fell short in races for state Senate District 13 and lieutenant governor in 2018. With her win on Saturday, she becomes the first transgender woman elected to the state Legislature."

    Republican Party Chuck Winder
    See also: Chuck Winder

    First elected in 2008, Winder had served as Idaho's senate president pro tempore since December 2020.[190] Winder lost the Republican primary to Josh Keyser (R) 52.3%–47.7%. Winder ran on his experience, with his campaign website quoting an editorial describing the incumbent as a "force of stability...a true conservative," saying Winder had "stepped up to oppose extremism while many others have remained silent."[191] Keyser ran as a political outsider, saying he would "offer a fresh perspective to help navigate the complex challenges we face in our beautiful state."[192]

    Idaho media identified Winder's opposition to the Idaho Freedom Caucus as an element in his defeat. Ahead of the 2024 legislative session, Winder removed two caucus members from committee leadership positions and disciplined a third, saying the members had posted content on social media that was defamatory to fellow legislative Republicans. Following the removal, the Republican Party of Ada County—Idaho's largest county—censured Winder.[193] In an interview with the Idaho Press, Winder said his opposition to the affiliated Idaho Freedom Foundation was a factor in his defeat.[194]

    Republican Party Greg McCortney
    See also: Greg McCortney

    First elected in 2016, McCortney had served as Oklahoma's senate majority leader since October 2021 and was selected earlier in 2024 to serve as president pro tempore after the 2024 elections.[195][196] McCortney lost the Republican primary to Jonathan Wingard (R) 51.8%–48.2%. McCortney said he was running "to continue working for the things that make our area truly special things [sic] like our conservative values, strong schools, an improved economy, protecting our natural resources and promoting agriculture and energy."[197] Wingard ran on his military experience and values, saying he would "fight for you as a conservative, value-driven Oklahoman...It is my honor and privilege to ask you to join me as we fight the good fight of faith, freedom and rights."[198]

    KFOR political analyst Mike Turpen said the earlier timing of the 2024 legislative primaries as well as McCortney's business as a legislative leader were factors in the election because they left the incumbent with less time to campaign: "Everybody’s telling me this move, moving the election up a week… It cost him and others the ability to go campaign at home...And that was critical time lost on the campaign trail."[199] In an interview with KGOU, political science professor and district resident Christine Pappas said the results were a surprise: "It just kind of seemed like a regular old campaign where you expect the incumbent to win with 65%, 70% of the vote. And it was just quite shocking to see the outcome, which had Wingard narrowly beating McCortney. In fact, McCortney won no counties."[200]

    Republican Party Craig Blair
    See also: Craig Blair

    First elected in 2012, Blair had served as West Virginia's senate president since December 2020.[201] Blair lost the Republican primary to Tom Willis (R) 44.4%–32.2%. A third candidate, Michael Folk (R), received 23.4% of the vote. Blair ran on his experience in leadership, with his campaign website saying he "passed major reforms that led to more people working and being paid higher wages than ever before," "led the effort in the state legislature to pass the largest tax cut in history," and "passed the most pro-life legislation in state history which made abortion illegal in West Virginia."[202] Willis ran on his military experience and his involvement in the community, saying he was "the leader we need to build a better West Virginia."[203]

    Local media coverage discussed Blair's loss in the context of other incumbent defeats in the state senate. Blair was one of four state senators to lose a primary out of the 14 who filed for re-election in 2024. West Virginia MetroNews correspondent Brad McElhinny said Blair emphasized different policies than his two challengers: "Blair was conservative but emphasized his passion for economic development, for growth in West Virginia...The other two guys, Willis and (Mike) Folk, were much more animated by cultural issues." In an interview with MetroNews, consultant Greg Thomas said the district's demographics worked against Blair: "It’s the fastest growing part or [sic] the state and you have a lot of new voters which diminishes the power of the incumbency."[204]

    Ballotpedia's 14th Annual State Legislative Competitiveness Report analyzed all 5,807 state legislative seats that were up for election on November 5, 2024, in 44 states.

    State legislative competitiveness in 2024 was below average for even years from 2010 to 2024.

    In 2024, the nationwide State Legislative Competitiveness Index was 33.2, down from the last three election cycles: 2022 (36.6), 2020 (33.4), and 2018 (36.1).

    State legislative competitiveness in 2024 (33.2) was below the 14-year competitiveness index average of 34.0. This average was for even-year elections only. Looking at averages across the last three even-year election cycles: 2024 had fewer open seats, incumbents in contested primaries, and seats with major competition.

    Key findings of this report include:

  • 962 seats were open (16.6%). This was the second-smallest number of open seats since Ballotpedia began gathering data in 2010.
  • 1,039 incumbents faced contested primaries (21.4%). This was roughly average compared to previous years, down from 26.8% in 2022 but higher than the 20.1% in 2020.
  • 3,583 seats were contested by both major parties (61.7%), higher than in 2022 (59.2%) but lower than in 2018 (66.3%) and 2020 (65.2%).

    Open seats

    See also: Open seats in state legislative elections, 2024

    There were 5,807 state legislative seats up for election on November 5, 2024, in 44 states. Of that total, there were 962 open seats, guaranteeing at least 17% of all seats would be won by newcomers. This was the second-smallest number of open seats since Ballotpedia began gathering data in 2010.

    Ballotpedia uses the number and percentage of open seats to help determine the overall competitiveness of an election cycle. A greater number of open seats guarantees more newcomers entering legislatures and typically results in more candidates running for office. A smaller number of open seats guarantees fewer newcomers and typically results in fewer candidates running for office.

    In 2024:

  • There were 407 open Democratic seats, those most recently held by Democrats at the time of filing.
  • There were 545 open Republican seats, those most recently held by Republicans at the time of filing.
  • There were 10 other open seats. This includes those most recently held by minor party or independent officeholders at the time of filing.
  • The total number of open seats—962—was higher than in 2020 (876), the last time all 44 states held elections, representing a 10% increase.

    Incumbents in contested primaries

    See also: State legislative incumbents in contested primaries, 2024

    There were 5,807 state legislative seats up for election on November 5, 2024, in 44 states. Overall, 4,853 incumbents filed for re-election and were running at the time of their respective primaries. Of that total, 1,039 incumbents faced contested primaries, representing 21% of all incumbents who filed for re-election. This was roughly average compared to previous years, down from 27% in 2022 but higher than the 20% in 2020.


    Ballotpedia uses the number and percentage of incumbents in contested primaries to help determine the overall competitiveness of an election cycle. A larger number of contested primaries indicates more opportunities for voters to elect a non-incumbent to office. A smaller number indicates fewer of those opportunities.

    In 2024:

  • There were 365 Democratic incumbents in contested primaries, representing 17% of all Democratic incumbents who filed for re-election, a 26% decrease from 2020.
  • There were 674 Republican incumbents in contested primaries, representing 26% of all Republican incumbents who filed for re-election, a 32% increase from 2020.
  • The total number of incumbents in contested primaries—1,039—was higher than in 2020 (1,006), the last time all 44 states held elections, representing a 3% increase.

    Major party competition

    See also: Major party competition in state legislative elections, 2024

    There were 5,807 state legislative seats up for election on November 5, 2024, in 44 states. Of that total, 2,224 (38%) were uncontested and had no major party competition. This was roughly average compared to previous years, down from 41% in 2022 but higher than the 34% and 35% in 2018 and 2020, respectively. The remaining 3,583 (62%) seats were contested by both major parties.

    Ballotpedia uses the level of major party competition to help determine the overall competitiveness of an election cycle. A larger number of seats without major party competition indicates fewer options on the ballot. A smaller number indicates more options.

    In 2024:

  • Democrats were guaranteed to win 1,111 seats (19%) that lacked Republican competition, an 8% increase from 2020, the last time all 44 states held elections.
  • Republicans were guaranteed to win 1,109 seats (19%) that lacked Democratic competition, a 10% increase from 2020, the last time all 44 states held elections.
  • Overall, Democrats ran for 4,694 seats (81%) and Republicans ran for 4,692 (81%).
  • There were four seats guaranteed to minor party or independent candidates because no major party candidates ran.

    Margin of victory

    Across all 5,807 seats up for election, the average margin of victory was 27.3%. An electoral margin of victory (MOV) is the difference between the share of votes cast for the winning candidate and the second-place candidate in an election. Only races with more than one candidate were included in this average. The chart below displays the breakdown of races by the winner's partisan affiliation and margin of victory for each state legislative chamber with single-member districts which held elections in 2024. A darker shade of red or blue indicates a larger margin for that party. The table below displays how many seats were up for election in each chamber and how many seats each party won. It also includes a breakdown of how many seats Democrats and Republicans won by 10% or less and without opposition in each chamber, as well as the average margin of victory for each party.

    Political context

    In the previous election cycle, Democrats gained control of four chambers: the Michigan House and Senate, Minnesota Senate, and Pennsylvania House. Additionally, in Alaska, a bipartisan governing coalition comprised of Democrats and Republicans won control of the Alaska Senate. Republicans previously controlled all five chambers.

    Changes in chamber partisan control, 2010 to 2023

    See also: Partisan composition of state legislatures

    From 2010 to 2023, 41 chambers switched control: 21 switched control once, 15 switched control twice, four switched control four times, and one—the New Hampshire House of Representatives—switched control five times. During that same time, there were 58 chambers that did not switch control.

    Before the 2010 elections, Democrats controlled 60 of the country's 99 state legislative chambers, Republicans controlled 37, and neither party controlled the remaining two chambers. After the 2023 elections, Democrats controlled 41 chambers and Republicans controlled 56. Multipartisan majorities controlled the Alaska Senate and House.

    Most changes in partisan control came from major elections, but some also came through special elections (Louisiana House in 2010; Washington Senate in 2017) and party-switching (Louisiana House in 2010; Mississippi Senate in 2011). In some cases, the party that gained control did not have a numerical majority but instead controlled the chamber through a bipartisan coalition (i.e., Alaska House in 2016). This table does not account for changes in party control or ties in a chamber that lasted for less than one year and were not the result of a regularly scheduled election. An example of this is the brief period of Democratic control in the Virginia State Senate in 2014.[207]

    For this chart, a red box indicates that the chamber changed from Democratic to Republican control, and a blue box indicates that the chamber changed from Republican to Democratic control.[208]

    Trifectas from 2010 to 2023

    See also: State government trifectas

    A state government trifecta occurs when one political party controls the primary levers of power in a state: the governor's office, the state Senate, and the state House. From 2010 to 2018, the Republican Party increased its number of trifectas and the Democratic Party saw a decline in its trifectas. Democrats picked up six trifectas in the 2018 elections, and Republicans lost four trifectas. Following the 2021 elections, the Democratic trifecta in Virginia became a split government after Republicans gained control of the state House and governorship. After the 2023 elections, the divided government in Louisiana became a Republican trifecta when Jeff Landry (R) won election as governor.

    This chart shows the number of trifectas each party held heading into elections from 2010 to 2023, and the number of trifectas following the 2023 elections.
